Summary
Connects Claude to Abnormal Security's threat detection platform via their REST API. You get tools to query detected threats, inspect individual messages with AI analysis breakdowns, trigger email remediation actions, review abuse mailbox reports, and manage security investigation cases. Uses a decision tree pattern where you call abnormal_navigate first to pick a domain (threats, messages, remediation, abuse, or cases), then access domain-specific operations. Supports both standalone mode with direct API token auth and gateway mode for hosted deployments. Reach for this when you need Claude to triage email security incidents, investigate phishing campaigns, or automate response workflows against Abnormal's threat intelligence.

Interactive Threat Card (MCP Apps)
abnormal_threats_getrenders as an interactive threat card in MCP Apps hosts (Claude Desktop/web): subject, sender, attack classification, remediation status, and the messages in the threat. The card is read-only — remediation stays a deliberate, model-mediated action. Plain-JSON behavior is unchanged in other hosts. Neutral by default, brandable viawindow.__BRAND__injection orMCP_BRAND_*env vars (MCP_BRAND_NAME,MCP_BRAND_LOGO_URL,MCP_BRAND_PRIMARY_COLOR,MCP_BRAND_ACCENT_COLOR,MCP_BRAND_BG,MCP_BRAND_TEXT) — no rebuild needed.
Authentication
Abnormal Security uses Bearer token authentication.
Standalone (env mode)
export ABNORMAL_API_TOKEN=your-api-token
node dist/index.js
Generate your token in the Abnormal portal under Settings > Integrations > API.
Gateway mode
When deployed behind the MCP gateway, set AUTH_MODE=gateway. The gateway injects the Authorization: Bearer {token} header automatically on each request.
Running

npm install
npm run build
node dist/index.js
HTTP Streamable (for hosted/gateway deployment)
MCP_TRANSPORT=http AUTH_MODE=gateway node dist/index.js
